I've heard about them and I found a gestalt generator, and it seems that they're a combination of two classes, but what are the rules for them, and in what book can they be found (I don't own it, but I might want it)?
As others have said, Unearthed Arcana. We use Gestalt in our campaign currently because we only had 3 players at one point (have 5 now). We've been at this campaign for a long time (over a year). Currently 13th level.
We've got a paladin/cleric, a monk/sorcerer, fighter/rogue, monk/fighter and a ftr/rogue2 + barb/monk11 (me).
We treat a combo as a "class" for multi-classing. So if I take 4 levels in a different combo that I already have I'd get an XP penalty. Also, we use variant rules to determine saves otherwise they get out-of-hand when multi-classing gestalt. A ftr/rog1 + ftr/rngr1 would get +2 fort +2 reflex twice using standard rules. Our variant treats you as having 2 levels of good fort and reflex and 2 levels of bad will.
Gestalt is a significant power up even though you can only do 1 thing a round. Combining ftr BAB with a monk is uber. Giving casters higher HD as other perks makes a big difference, they are no longer squishy. Rogues with ftr BAB are insane damage dealers with TWF. Characters become more survivable (better saves/HP) and more flexible.
My ftr/rog2 barb/monk11 has greater flurry, greater rage, DR 2/-, movement of 70ft, AC 26 (nothing fancy), improved evasion, immune to poison, wholeness of body, whirling steel strike, whirlwind attack, uncanny dodge, slow fall, and UMD.
We use house rules where everyone gets able learner free and if you meet the stat reqs you get combat expertise and power attack free.
Combining monk once you get to the higher levels is powerful. SR, extra attacks, grappling/unarmed abilities, extra movement, immune to poison. Monk combines well with anything. Monk/rogue plus stunning fist then sneak attack. Monk/cleric of heironeous with whirling steel strike. etc. etc.
